It contains all the extensions to the AT91 architecture that are necessary to integrate the new ARM9 processor family members of the growing Atmel AT91 processor family. One main objective of this patch is to ensure the existing ports do not break because of these extensions. This is done by changing as little as possible to the existing headers, like var_io.h, while opening a way, how to integrate new processor without touching these central header files all the time. There are however a few bug-fixes included that may be of interest to other ports as well: - THUMB Mode was broken (did not compile) It does compile now, and is tested on AT91SAM9G45 platform. - Fixed FIQ Enable Mode: FIQ CPSR Flag was task specific. - Fixed Spurious Interrupts Crash. - Fixed ARM_ICE_THREAD_SUPPORT. Must keep that at 0ffset 0x50. - AT91SAM7s: Diag Port=UART2 did not compile. - Fixed recv from debug port with serial line speed > 38400 baud. - Enhanced accuracy in hal_delay_us() with PIT timer. - Fixed overflow in hal_delay_us() with TC timer. - Fixed crash in hal_if.c when no Debug port is configured. (by Number of communication channels on board = 0, Debug serial port = -1) - Fixed compile error in arm_stub.c in some configurations. -- You are receiving this mail because: You are the assignee for the bug.
